Configuration procedure
1. Configure an IGP on each MPLS backbone to ensure IP connectivity within the backbone.
This example uses OSPF. (Details not shown.)
Be sure to advertise the 32-bit loopback interface address of each router through OSPF. The
loopback interface address of a switch is to be used as the switch's LSR ID.
After the configurations, each ASBR PE and the PE in the same AS can establish OSPF adjacencies.
Issue the display ospf peer command. The output shows that the adjacencies reach Full state, and
that PE and ASBR PE routers in the same AS can learn the routes to the loopback interfaces of each
other.
Each ASBR PE and the PE in the same AS can ping each other.
2. Configure basic MPLS and enable MPLS LDP on each MPLS backbone to establish LDP LSPs:
# Configure basic MPLS on PE 1 and enable MPLS LDP for PE 1 and for the interface connected to
ASBR-PE 1.
